I probably ought to explain my own as OP... ;-)
I see people charitably giving skaters another chance as their careers were cut short by injury or they never reached early potential etc. Others are looking back in time curious as to how certain skaters would fare now.
However, I am just going to be very selfish and choose a recent retiree already mentioned just because I adore him and would give anything to magically give him another few years of skating at his top form (and with the will to do so of course) and without injury: Daisuke Takahashi. He just left me breathless when I watched him and mesmerised by the intensity of his art. For feeling and enhancing every beat of the music, he was untouchable. It would be worth expending my magic just to see one more glorious step sequence.
It's not selfish at all for Daisuke, I would want to give him a chance too, he was injured in his last season and couldn't even go to Worlds, he also had that torn ACL injury that too him out for an entire season. He's had a lot of injuries and I would love to see him skate at top form again. It seemed like when he retired he had some regrets because he couldn't perfect performances.
